so around 3000-4000rpms, when im at 3/4 - full throttle, my car starts to buck a bit.. any idea what this could be?

 

Check for codes?

MAF?

 

MAF dude.

 

there are no codes for the maf, and although it bucks a bit it keeps going... also it doesnt happen in first gear, only in 2nd and 3rd...

 

Are you still on your stock coils?7

 

I am on my stock coil packs but ive replaced one of them and it threw on on code when i did.. Could it be my spark plugs?

 

anybody got ANY ideas? please help!

 

could be a slight fuel problem...Do you have an AFC or Eu.....Could also be the very first sign of the fuel pump taking a dump....

 

doesn't a bad MAF cap your RPM at 2500? so it rules that out.

 

you could check and see if all your coil packs are running right
(emitting the right spark whatever)

 

i think its a fuel problem.......perhaps water in the fuel.cud be wrong

 

What maintenance have you or have you not done?
What is your mileage?

 

After I took my throttle body apart for cleaning .... like an a-hole i took off the tps. I put it on and didn't think anything of it. My car kept bucking like crazy but only at certain rpms. I adjusted it and there has been no more bucking.

 

Ok.. So my cheap generic code reader wasnt pulling up the code but it is cylinder 5 misfire i havnt changed my plugs yet and my car is at 78000 miles so im going to try that first got the plugs just need time to install them.. and i will check my coils with on on multometer the second i get my hands on one thanks everyone for your help!!!

 

If cylinder 5 is misfiring then your coil there has gone kaput...Change that and everything should be back to A ok...

 

 

why are you even on here? in fact, why did you even register?

 

good idea

 

"juss hit the blunt and smoke out the car and think bout it later" ??~?~

you must drive a civic, so: :stfu:

 

^^haha^^

 

Pull the coil first, plug it back in and plug in a spare spark plug, hold it to the intake manifold while you or assistant starts car, the plug can cause misfire code as well.

 

have you changed you fuel filter? I had that same problem so I replaced mine and it helped a little but not all the way but I also have a bad O2 still gotta replace that. and if you do replace your filter I was told get a 300zx filter.

 

I would try the following ::: new plugs first - if that doesn't do it, then do the coil pack. If the new plug and / or coil pack doesn't do it, try replacing the fule filter.

At first ... I though, learn how to shift mate! but ... I agree if you're pulling codes, that must be the reason! lol G'luck, keep us posted please.
